BINDING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 266,738, dated October31, 188.9,

Application filed August 17, 1982.

To all whom it may concern Be it known that l, RICHARD J. WnLLns, ofChicago, county of Cook, and State of lllinois, haveinvented certain newand useful In]- provementsin Binder Attachments for Sewing- Machines, ofwhich the following is a specification.

Thisinvention relates to binder attachments for sewingmachines, and hasbeen designed to more especially for use in harness-making, but iscapable of employment upon the ordinary domestic sewing-machine,and forother uses.

The invention consists- First, in the combination, with a sewing-machineand binder, of a device for uicking or notching the binding material toenable the application thereof to a corner of the article being bound.This operation has usually been done heretofore by the operator with theaid of scis- 2o sors or some equivalent device.

Second, in the combination, with a sewingmachiue and binder, of anotehing or uicking device and a gage, whereby the operator may know inadvance where the nick should be cut and be enabled to stop the machinewhen the right point has been reached.

Third, in the novel construction of the nicking device and the gage.

Fourth, in the construction of the binding 0 device; and,

Fifth, in the combination, with a sewingmachine and binder, of apressure-roller, all substantially as hereinafter set forth.

In the accompanying drawings, Figure 1 is a plan view of my improvedbinder and nicking attachment. Fig. 2 is a front view ofthe same. Fig. 3is an edge view of the pressureroller and the parts by which it iscontrolled, and Fig. 4: is a bottom view of the same. Fig.

5 is a section of the binder, upon the line 00 w of Fig. 2. Fig. 6 is aplan of all the parts as they appear when in use and attached to the bedof asewing-machine. Fig. 7 is a side view of the uicking device, uponthe line 3 y of Fig.

1, with the nickingtool poised, ready for an operatlon.

In the drawings, A represents the bed of a sewing-machine; a,the needle,and a the presser-foot thereof.

B represents a slotted plate, by means whereof, in conjunction with theset-screw a, the

(No model.)

binder and uicking device are secured to the bed A. To this plate aresecured upper and lower spring-leaves, I) b, having guiding-projectionsb I), which may be concaved, as shown, 5 affixed thereto, each of saidprojections serving as a guide to one edge of the binding material. Theedge of the material to be bound, with the binding in position upon it,passes between the spring-leaves and under the pressure-foot and needle,being kept at all times as it progresses in contact with theanti-friction guiding-rollers I1 12 having bearings in the plate B. Thelateral force necessary to keep the material up to the guide-rollers bmay be manual force; or it may be exerted by the grooved roller 0,mounted upon a lever, c, pivoted upon the pivot c in the bed A, themanual force in the latter case being exerted upon the lever. I muchprefer,wherethematerial oper- 7o ated upon is stiff enough to permit, touse this roller 0, as it enables the operator to maintain a steady, evenpressure, avoids the necessity of releasing and taking hold of thematerial at frequent intervals, and saves the strength and hands of theoperator.

The spring-leaves are adjusted to the different thicknesses of materialto be operated upon by the screw b and they are adj ustable toaccommodatedifferentwidthsofbindingbybeing 8o slotted longitudinally atthe points Where they are secured to the plate B by screws L b In manyclasses of work this binder will be found very useful, as it avoids manyevils incident to the binders now in use. Among these evils I willmention the stopping of the feed by the friction upon the material,caused by the guiding devices. This friction is done away with by mydevice.

A lateral projection, D, of the plate B serves as the gage-plate andsupport for the uicking device. It is provided with a diagonal ridge ormark, at, and is slotted upon the same angle at d to permit theadjustment of the uicking device. This device consists of a knife, (1 in5 L form, secured upon an arm, (1 pivoted to the slide d, which latteris secured to the part D by the screw (1 passing through the slot (3.For convenience, a knob, (1, may be provided upon the arm d whereby tolift and operate too said arm. Gage-marks m upon the part D may becontinued back of the diagonal line (Z at right angles to the latter; orother divisionmarlzs may be placed thereon. The diagonal line (1 shouldbe at such an angle to the line of feed as will enable the bindingmaterial to be drawn aside from the article to be bound suffieiently toenable the cutter to descend and nick the former without touching thelatter.

In the use of this part of the device I so cate the knife that its apexand the gage-mark, by which it is known that the timet'or' nicking thebinding has arrived, will lie in the same circle, having the needle forits center. This is illustrated in Fig. 6, where the dotted line 0indicates the circle mentioned. The operator knows when to stop themachine and notch the binding by the fact that the end or corner of thematerial next in order for binding has reached the gage-mark, as clearlyindicated by said Fig. 6; and when the work has progressed thus far thefree binding is drawn to one side upon a line with the line (I, thecutter is swung over from the open or thrown-back position in Figs. 1and 6 down upon the binding and a notch cut therein. After cutting thenotch. which of course is done in both edges of the binding at the sametime, the binding is moved back into line with the feed and the sewingresumed.

I find it convenient, when the material being bound has short sides orends, to place the notching-knife at such a distance from the needlethat when one corner upon the narrow edge is directly under the needlethe next corner upon the same edge will be at the exact positionrequired for the next notching operation. This is permissible of courseonly when such narrow edges come within the dimensions of thegage-plate.

That portion of the gage-plate which receives the impact of thenotching-knife may be made of soft metal or equivalent material, ifdesired.

I claim- 1. The combination, with the sewing-machine and binder, of adevice for notching the corners of the binding material, substantiallyas specified.

2. The combination, with the sewing-machine and binder, of a device fornotching the binding material and a gage for determining the pointsatwhich the notches are to be cut, substantially as specified.

3. The nicking(levieeconsisting oftheswinging arm, provided with anL-shaped cuttingedge, combined with the slide and the supporting-plate,substantially as specified.

4. The notch-eutter hinged to the gage-plate, provided with the diagonalline (1, in combination with such gage-plate, substantially asspecified.

5. The binder consistingof the spring-leaves, having guide-projectionsthereon, and the antifriction rollers for guiding the material to bebound, substantially as specified.
